Spokane vs Boise: which is more affordable?

These multipliers are based on Bureau of Economic Analysis Regional Price Parities and reflect average housing, food, transportation, and services costs. Real personal costs vary by neighborhood (urban core vs suburb), housing choice (rent vs own, apartment vs house), and lifestyle (frequency of dining out, car-dependent vs transit, etc.).

What costs more (and less) in Boise

Cost of living differences are driven mostly by housing — typically the biggest expense category. Boise's housing index (0.70×) compared to Spokane's (0.63×) is the dominant factor.

Food, groceries, and transportation typically vary 5–15% between metros — much less than housing. For a couple moving from Spokane to Boise, expect roughly:

  • Rent / mortgage: 11% higher
  • Groceries: 2% higher
  • Transportation: 2% higher
  • Healthcare, services: roughly proportional to overall index

Things this calculator can't fully capture

  • Quality-of-life: weather, walkability, school quality, crime rates, commute times — not in the index.
  • Career opportunities: a metro with higher cost-of-living often pays correspondingly higher salaries for the same role. See our salary calculator by job and city.
  • Family situation: childcare, school district, eldercare costs vary independently of overall index.
  • Lifestyle preferences: a frugal renter pays less than the index suggests; a property owner in a hot market might pay much more.
